WICKLESS OIL BURNER.

Application iled September 1, 192 Seral No. 585,733.

T 0 all whom t may concern:

Be it known that I, VILLIAM MEXERS, a citizen of the United States, and a resident y of Lima, inthe county of Allen and State of Ohio, have invented certain new and useful Improvements in Vickless Oil Burners, of which the following is a full, clear, and einact description.

My invention relates to wickless oil burn- .10 ers and one of the objects of the invention is to provide a burner of this character which will produce substantially perfect combustio'n, thereby eliminating smoke and disagreeable odors.

Another advantage of my burner is that it is rectangular in form whereby a greater heating surface -is obtained than in the'usual circular burner of the same size.

A further object of the inventionis to pro2 vide air inlets of the proper size and .properly located, to produce the best results.

Still another object of the invention is to so construct the same that drafts of iair will have very little if any effect on the b urner.

Another advantage of the invention4 is that the various parts are soconstructed that they may be easily and quickly assembled or diassembled.' f

A further object of the invention resides in the provision of numerous ridges in the Combustion chamber thereby materially assisting in a thorough mixing of the `gases.

Another advantage of the invention resides in the provision of a fuel feed pipe l highly polished on the interior, thereby assuring a constant and steady supply of fuel.

Another object of the invention is to provide a`burner of this ACharacter which is eX- tremely neat in appearance'and highly eiiicient in operation, and yet is relatively inex- V pensive in manufacture.

Other objects and advantages of the in-.

vention will be apparent to those skilled in the art, from-the following detailed descrip` ton when taken in connection with the'accompanying drawings; in which,

Figure 1 is a vertical section through the burner; the fuel feeding apparatus being shown infelevation.

Figure 2 is a plan view of the burner. Figure 3 is a side view of the burner. Figure 4 is a horizontal sectional view taken on line 4 4 of Figure 1.

Referring to the drawings more in detail,

-4 numerall indicates the burner'base plate, which 1s rectangular in shape and is pro# vided with aperturedjspacing and attaching lugs 2 at each corner thereof. A shoulder 3 isprovided in 'the base plate adjacent the edge thereof, and extends entirely around the same. This shoulder 3 is provided for the reception of the burner'shell 4,- which also is of course rectangular in cross-section and has the walls thereof inclined upwardly, 4so that it has vthe shape of a frustum of a pyramid. yAn asbestos pad 5 is employed between the lowerend of the shell and the. base plate, and also between the outer wall of the shell and the shoulder 3 of the base plate.

Spaced inwardly from the first-mentioned shoulder4 3 is a second shoulder 6, and outwardly of this shoulder is arranged an upwardly extending flange 7. A trough or lgenerator 8 is mounted on the burner plate and is positioned thereon by the shoulder G, an' asbestos mat being positioned between the generator and burner plate. and between the generator and the ange 7. The generator 8 is rectangular in cross-section and the inner wall thereof extends to a slightly greater 'height than the outer wall.

The combustion chamber, indicated generally by numeral 9, is formed/of ank inner wall 10 and outer wall 11. Both walls are rectangular in -cross-section and each wall is provided with a shoulder at the bottom therei of for engagement with the walls of the generator.

A cover 12 is mounted on the top of the burner shell and the outer wall of the combustion chamber. the cover being provided .withlugs'on the inner and outer edges for engaging the combustion chamber wall and the burner shell. The burner shell, the outer wall of the combustion chamber, the cover and the burner base plate. define the outer air space 13, air being admitted to the air space through a suitable. number of air holes 14.

Mounted on the top of the inner wall of the combustion chamber is a burner top plate 15 which is cast hollow and has downwardly extending lugs 16 for engaging the combustion chamber wall. The top and bottom walls of the burner top plate are provided with sma-ll holes 17 to permit the escape of air in case the pressure should become too great. The burner top plate and the inner wall of the combustion chamber form the inner air space, indicated by numeral 18. A bolt 19 engages at its lower end with a spider 2O formed integral with the burner base plate, and at its upper end it en gages the burner top plate. By screwing down on the nuts provided it will be apparent that the burner top plate, the inner wall of -the combustion chamber, the' generator and the burner base plate, will all be firmly and securely connected.

A pressure plate 21 is mounted over the cover 12, and is spaced therefrom by means of spacing shoulders v22.y the pressure plate also being provided withlugs 23 for engaging the burner shell. `Numeral 24, Figure 3, indicates the. opening between the cover 12 and the pressure plate 21, whereby air is permitted to freely enter thc space formed by the two plates. It is to be noted that the inner edge of the cover 12 is spaced inwardly from the inner edge of the pressure plate 21, for reasons to appear hereinafter.

Bolts 24, engage the burner base plate and the pressure plate, and by taking up on these bolts the pressure plate, the cover, the

outer wall of the combustion chamber, the4 generator, and the burner shell are all firmy connected. v

The inner and outer wall 0f the generator are rovided withy small air holes 25, communicating with the' inner and outer air chambers respectively. The inner and outer wall of the combustion chamber have numerous ridges 26 formed thereon, and the walls are also provided with a great number of small round holes 27, communicating respectively with the inner and outer air chainber. Adjacent the top of the outer wall of the combustion chamber, are a plurality of air slots 28 for admitting additional air from the outer air chamber.

A fuel feed pipe 29, inclined at the proper angle, leads through the burner shell into "theinterior of the generator, being attached thereto by screw-threadedly engaging a lug` 30 formed on the outer wall of the generator. A sight feed valve 31, of well known construction, is attached to the feed pipe, and a priming cup 32 also communicates with feed ipe.

p ln operation` the generator is primed and ignited, and when the burner is thoroughly heated the valve 31 is operated to start the feed of fuel, which may be kerosene, gasoline, alcohol, etc., but ordinarily kerosene will be used as fuel. The oil flows through the pipe 29 into the generator, and itishould be mentioned here that the interior of the pipe 29 is highly polished, whereby the feed of fuel is maintained constant.

n the generator the oil is vaporized Iinto a grey vapor, and as the vapors pass up- Y Wardly from the generator they combine Y Laser/a with air forming a combustible mixture which burns with a blue flame. 'The air for supporting combustion is supplied in the following manner:

The burner base plate l is spaced from the stove plate by spacing lugs 2, and 'the air passes into the relatively shallow space between the two plates, then through holes 14 into the outer air space, and through the open bottom of the inner combustion Wall into the inner air chamber. From the inner and outer air chambers the air passes into the top ofthe generator through the holes 25, and into the combustion chamber through the holes 2T. AAs the gases pass upwardly through the combustion chamber, th'e ridges on the walls thereof cause the gases to thoroughly intermingle, thereby greatly assisting in obtaining comlete combustion.

At the topv of the combustion chamber.

there is asupplementary air supply to assure complete combustion. For this purpose air slots 28 are provided, and also additional air is supplied through the space between `the pressure plate 21 and the cover 12, the

inner edge of the pressure plate being spaced `outwardly from the inner edge of the cover,

vwherebyl the additional air is permitted to pass freely upward. Any excessive pressure developed in the inner air chamber will be permitted to escape through the openings 17.

` In oil burners it is highly important that air drafts be avoided, and I have accomplished this in my burner by means of the shallow air space between the stove plate and the burner base plate. and between the pressure plate and the cover. By making these spaces shallow and open on all sides, air drafts have practically no effect on the burner.

From the foregoing detailed description it will be apparentA that l have devised a burner possessing numerous advantages over previously known burners of this type. The

burner being rectangular in shape provides number of the air'holes should be increased While the size thereof remains the same.

In accordance with the patent statutes l' have described what I now believe to be the best embodiment of my invention, but I do not wish to lie'vlinderstood thereby as limitn ing myself or the scope of my invention, as many modifications may be made without departing from the spirit of the invention, and all such I aim to include in the scope of the appended claims.
